LastPass Heartbleed tester – input the domain name – Lastpass checks the certificate date, and some sites will fail — that passed the previous 2 tests.

Remember to check the domain using all 3 tools. If the domain passes all 3 tests, then it’s OK, and your next step is to create a new password. Remember to change your password to a new, totally unique, strong password – preferably at least 15 characters long. If the website in question does not pass all 3 tests (listed above), then it’s best to NOT use the website. Contact the company that owns the website by phone or email and ask them how soon the website will be fixed.

Remember to test all the websites you normally visit, and change ALL your passwords to strong, unique, new passwords.

NOTE: If you are a system administrator, you have a lot more work to do. Read everything here and here first, and don’t rely (only) on the tests provided above.
